v0.13.0

chore: release v0.13.0

Register Microsoft Store submission identity for the desktop .msix
(MSIX_IDENTITY_NAME/MSIX_PUBLISHER/MSIX_PUBLISHER_DISPLAY repo variables),
keeping the confy display name and CLI/repo/domain unchanged.

macOS note

The .dmg is not notarized, so macOS reports the app as "damaged".
After copying confy.app to Applications, clear the quarantine flag:

xattr -cr /Applications/confy.app
